ABSTRACT:
A pivotable seat assembly for a mobile vehicle that allows the seat to be adjusted in fore or aft directions, pivoted to a position facing either of the directions, and then releasably latched against pivoting. The seat assembly includes a vertical support shaft member securable to the vehicle with a freestanding end having a primary abutment thereon; a rotatable support frame member having a top portion with the support frame member being rotatably mounted on the support shaft member so that the primary abutment projects beyond the top portion; a carriage for supporting the seat on the rotatable support frame member for sliding movement to a limit position; a latch assembly for selectively preventing rotation of the rotatable support frame member operatively connected between the support shaft and the rotatable support frame including, a fixed latch secured to one of the members, a shiftable latch mounted on the other member for movement into and out of engagement with the fixed latch, and a biasing spring for normally biasing the shiftable latch into engagement; a primary stop mounted on the carriage for movement therewith in the fore and aft directions and contactable with the primary abutment to define the carriage limit position; and a latch actuator mounted on the carriage for movement therewith into contact with the shiftable latch to move it out of engagement with the fixed latch and permit pivoting of the seat when the primary stop is in contact with the primary abutment to limit the amount of stress applied to the shiftable latch and the slidable carriage.
